Literally any instructions what so ever would’ve been helpful
Comes in a bag dissemebeled in four different pieces. No directions. Otherwise looks like it will be a nice product.

Solid product
Looks great and a solid build with the colour suiting my project bike. As fitted to an XR400 I had to reuse the last OEM bolt but a nut comes for it. I preferred to paint the bolt heads black to suit.

BETTER THAN STOCK
Fraction the cost of some others.Good quality.Went together quickly.No instructions.(Real men don't read them anyways)Only have about 4 hrs use on it,but shows no wear at all.Stock guide would have been about half gone by now.This guide has larger side openings for dirt/mud to clear out easily.

First look
I just received this from RMATVMC, and it is a nice piece, bolted right up, no fitment issues, looks good. haven't got any miles on it so far, there is still 2 feet of snow on the ground here, so I cant comment on durability, but judging by the appearance of quality, i think it will perform and last a long time.

Is this a two piece (i.e. Will I have to remove my chain to install?)i
William P on Oct 11, 2016
BEST ANSWER: Hi William. You do not have to remove your chain. It's very easy to put on and has lasted well for me so far. I'm very please with it and would buy it again for the cost.
Does this chain guide come with the mounting hardware?
A shopper on Apr 8, 2017
BEST ANSWER: When I ordered it, it did not come with it. However, the three bolts are common ones in the metric bolt box.
does it fit ok with a 48 tooth sprocket?
cole m on Mar 19, 2017
BEST ANSWER: Yes...it fits well...we even ran a 50 tooth. It's a well made product. My son races and practices everyday...holds up well.
will it fit a 53 tooth sprocket?
John T on Sep 20, 2017
BEST ANSWER: I no longer have the bike I installed this on but the unit is SOLID. I would expect it to fit any reasonable size rear sprocket that the bike itself can fit/is designed for. Worst case scenario you have to grind off a bit of the plastic wear guide or you keep your chain a bit longer so you axle is more rearward.
Does it fits on Honda XR250r? Motorcycle year is 2000.
A shopper on Sep 3, 2017
